SEWER-PiPE.

Specification of Letters Patent.

Patented June 25, 1907.

To (LZZ w/wm/ it Wtcty concern:

Be it known that I, JOHN M. PHELAN, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented a new and useful Improvement in Sewer-Pipe, of which the following is a specification.

This inventionrelates generally to a reinforced concrete pipe and more particularly to an improvement upon the reinforced concrete pipe'patented to me September 20, 1904, No. 770,383. In that construction of pipe the sections were locked together by means of a band assed around the exterior of the meetin en s of the pi e sections, and engaging the ookedends o the reinforcing bars or members.

The object of my present invention is to provide a connection entirely upon the interior of the conduit thereby enabling the. pipe sections to be arranged together in a ditch or trench and the connecting band inserted and locked entirely within the conduit, and with this object in view the invention members the ends of which projectbeyond the body portion of'the pipesection and are bent back upon itself providing hooks, the pipe section at one end being flanged and provided with a collarat the opposite end, the collar of one pipe section being adapted to fit into the flanged end of the adjacent section, the flan e being of greater depth than the collar thereby leaving an interior circumferential groove and into which roject the oppositely disposed grooved en s of the reinforced barsor members, the flanged end of the pipe having orifice which communicates with the internal circumferential groove and through which a fastening band can be inserted for the purpose of engaging members.

The invention consists also in certain details of construction hereinafter fully descri' ed, pointed out in the claims.

In the drawings forming a part of this specification '.Figure 1 is a sectional elevapipes constructed in accordance with my view taken on the line 22 of Fig. 1 the orifice being left open for the purpose of I lan view showsection in-accordance with my present invention,-I mold the pi eA ofconcrete or any other sui able materia and embedded therein are the longitudinal reinforcing bars or members B of metal, the ends B projecting be yond the opposite ends of the pipe sectioi said ends being bent back upon themselves asshown thereby providing hooks or hooked members, the purpose of which will appear hereinafter. One end of the pi eA is formed with a collanC, said collareing beveled as shown at C and the opposite end of the pipe is formed with an annular flange D, which is beveled at D to correspond with the bevel C of the annular collar C, it being understood that the flange D fits snugl within the collar C when the pi e sections are arranged in their proper or er for the purpose of constructing a sewer or conduit.

It will be noted that the collar. C is somewhat deeper than the flange D so that when the ends of the pipe are brought into engagement there is produced an interior circumferential groove E at the juncture ofthe two sections, and it will be noted that the hooked ends of thereinforcing bars extend into this circumferential groove and in putting the pipe sections together they are so arranged that the hooked members register with one another as most clearly shown in the drawings and for the purpose of con necting these hooked members together, I- .employ a metallic band F which band is inserted through an orifice G, produced in the flanged end of the pipe section, said orifice being preferably arranged tangentially so that the metallic band can be quickly and easily threaded into the interior groove and the operator upon the interior can feed the end of the band around between the op ositely disposed hooked members and aflier the entire band has been so threaded into the pipe it is securely locked by means of wedges H insertedbetween the band and the hooked members thereby securely locking the pipe sections together and preventing all possible displacement or longitudinal movement, and the orifice G and groove E are then filled with cement or concrete and a conduit or sewer is provided with an absolutely unbroken exterior and interior. The cement in the groove will also serve to prevent any dis placement of the keys. It will thus be seen that I provide an exceedingly simple and efficient means for fastening pipe sections together and entirely upon the interior thereof.

Having thus fully described my invention, What I claim as new and desire to secure by Letters Patent, is

1. A sewer pipe section having longitudinal reinforcing members, the ends of which are shaped for engagement with a locking band, one end of said pipe being flanged and the opposite end of the pipe provided with a collar, the collared end having an opening or orifice extending therethrough.

2; A sewer pipe section having longitudinal reinforcing bars, the opposite ends of which are shapedfor engagement with a locking band, one end of said pipe being flanged, the opposite end having a collar, the collar of said pipe being deeper than the flange and an orifice extending through the collar of the pipe at its inner end for the purpose specified A sewer pipe section constructed with a beveled flange at one end, a flange at the opposite end, said collar being of greater depth than the flange, the outer portion of said collar being beveled to correspond with the bevel of the flange and a tangential orilice extending through the inner end of the collar for the purpose specified.

' 4. A sewer pipe section having a collar at one e1; and a flange at the opposite end, V longitudinal reinforcing bars arranged in the pipe and having their ends projecting beyond said pipe, said ends being hooked, the collared end of the pipe having an orifice extending therethrough, and a band ada ted Q to be inserted through said orifice and a apted to engage the hooked ends of the-rein-- forcing bars when two sections are joined together as set forth;

5. A sewer pipe section havmg longitudi nalreinforcing bars provided with hooked ends, said pipe having acollar at one end and a flange at the opposite end, the'collar being deeper than the flan e and provided with an orifice extending t rough its inner 4 dinal reinforcing bars, the ends of which are shaped for engagement with a locking band,

and a collar at the opposite end, said collar i said pipe having a beveled flange at one end being of greater depth than the flange and beveled at its outer end to correspond with the bevel of the flange, the flange being adapted to fit into the collar when :the

ipe sections are assembled thereby providing an interior annular grooveat the juncture of two pipe sections, the collared end of the pipe having an orifice which communicates with said interior groove, a band'adapted to be inserted through said orifice, passed into the interior roove and brought into engagement with t e ends of the reinforcing bars and wedges adapted to be inserted into the ends of said bars between the bands and said bars for the purpose specified when two sections are joined together.
